1. A wireless communication terminal, the terminal comprising:
a transceiver; and
a processor,
wherein the processor is configured to:
receive, through the transceiver, a trigger frame that triggers a multi-user uplink transmission,
perform a multi-user uplink transmission in response to the received trigger frame, and
receive, through the transceiver, an ACK for the multi-user uplink transmission,
wherein when the multi-user uplink transmission is performed on a resource unit in which a temporary association identifier (AID) is assigned by the received trigger frame, the processor obtains ACK information for the terminal from the ACK for the multi-user uplink transmission based on the temporary AID,
wherein the AID comprises a first AID set consisting of one or more AIDs for AID assignment of each terminal in a basic service set (BSS) and a second AID set consisting of one or more AIDs not included in the first AID set, and
wherein the temporary AID is an AID in the second AID set.
